I am trying to convert code from mysql to mysqli. The code uses a single mysql_connect in a file which is included by every other file.
mysql_connect returns a MySQL link identifier that is a superglobal so you can rely on having a database connection available in any of your own functions.
It looks like with mysqli_connect this is not the case, the object returned isn't global.
Does this mean I have to add : global $mysqli; at the top of every function, or is there an way of making it a superglobal?
